Proportioning Valve Description

Proportioning Valve, Knob Style.

Adjuster knob with fine thread tuning provides precise pressure adjustment. This adjustment lets you fine tune the front to rear braking balance by proportionally decreasing the rear brake line pressure. Valves weigh only 5.2 ounces and have two .25” side mounting holes spaced 1.00” apart.

This valve varies from our standard Knob Style Proportioning valve, as the inlet and outlet ports are 10MM X 1 bubble flare seats and do not require tube nut adapters to directly install tubing with bubble flare 10MM x 1 nuts, which works with most vintage Japanese car brake lines. 

We recommend using this valve with our brake kits.
